As we all know there are many fonts in the world. Your computer contains a lot of fonts and there are many websites offering free fonts that people have created as well. Changing the fonts on your phone has always been possible, just not overly easy. Previously on Android you had to get a rom for your device with the different font built in or get the font in an update zip for Clockwork Recovery.
Using this app is very easy, as long as your phone is rooted. If not I would not read any more of this article. The app is installed from the Android Market for free and that is it really. The next thing to find is some fonts that actually look good. A simple search on Google for “Free fonts” brings up a lot of websites that let you download the tff files that this app needs. Copy the downloaded files to your sd card into the .fontchanger folder and your in business.
Some fonts may look a bit blurry, so check out the preview button before you commit to a font. If you do not like the results you can revert to default using the app as well. The app will change icon labels, app drawer labels, text messages, email, the clock font and basically every font on your device. You can find some really nice fonts that look great and add to a theme or rom nicely.
Below are some shots of the app and the result after applying a font.
I recommend Ubuntu font, looks very nice with Android. Download here: http://font.ubuntu.com/
